Imaging spectrum of spinal dysraphism on magnetic resonance: A pictorial review

Figure 12 Hemilipomyelomeningocele. T2 weighted sagittal (A), T1 weighted sagittal (B), T2 weighted axial (C) and T1 weighted axial (D) images in a case of hemilipomyelomeningocele. There is diastematomyelia with bony septum (white arrow) suggestive of type I diastematomyelia. There is defect in the posterior spinal canal on the right side through which the spinal canal contents herniate with intact overlying skin and subcutaneous tissue (arrowhead). There is expansion of subarachnoid space (+) anterior to the cord pushing the neural placode - lipoma interface posteriorly to lie outside the boundaries of spinal canal (arrow).
